METHOD OF FORMING LEADER TIES Filed May 17, 1952 Patented July 13, 1954 UNITED STATES OFFICE METHOD OF FORMING LEADER TIES Application May 17, 1952, Serial No. 288,577

2 Claims. 1

This invention relates to a method of forming a leader tie and particularly a leader which con- 'sists of a metal core or wire surrounded by a sheath of plastic material, such as synthetic polyamides (nylon), unplasticized vinyl resins (Vinyon), or cellulose acetate rayons.

Heretofore leaders of this sheathed type were very difficult to tie, due to the fact that the plastic coat, or cover, would tend to cause the leader to straighten out, and consequently a neat and small tie was very diflicult or almost impossible to achieve. Some manufacturers resorted to a knot, which is both large, clumsy and unsightly.

An object of my invention is to provide a method of forming a leader tie with a plastic coated leader, which is both simple and eiiective, and which will produce a small, neat and sightly tie.

Still another object of my invention is to provide a method of forming a leader tie of the character stated, in which the tie when completed, is still effectively covered or coated with the same plastic coating material.

A feature of my invention is to provide a method of forming a leader tie with a plastic coated leader in which a metal to metal wrap of the encased metal strand of the leader is accomplished in a simple, quick and effective manner, thus providing a tie which will not unwrap.

Other objects, advantages and features of invention may appear from the accompanying drawing, the subjoined detailed description and the appended claims.

In the drawing:

Figure 1 is a diagrammatic side elevation showing a mechanism by means of which the method of forming a leader tie can be accomplished.

Figure -2 is an enlarged side elevation of the leader tie.

Figure 3 is an enlarged fragmentary longitudinal sectional view of the leader tie.

Referring more particularly to the drawing, fishing leaders are now frequently made of a metal wire, or cable, which is completely covered or sheathed with a plastic material, such as synthetic polyamides (nylon), unplasticized vinyl resins (Vinyon), cellulose acetate rayons, and others. It is necessary to attach a swivel, or hook or other metal object to one or both ends of the leader, and this is accomplished by means of the tie i. This tie consists of'wrapping the end 2 of the leader around the main strand 3 to form a fixed loop 4, within which loop the metal swivel hook or the like is attached.

The wrapping portion 2 of the leader will be termed the wrapping strand, while the portion 3 will be termed the main strand. It is understood, however, that these are all part of one continuous length of leader material. To form the wrapped tie i a rotating chuck or head 5 is provided and the wire leader is attached to the hook t thereon, and consequently as the chuck 5 rotates, the wrapped tie I will be achieved. A weight 1 is attached to the end of the Wrapping strand 2 and the tie I rests on a table or support 8, so that the tie will not sag during the wrapping operation.

As the wrapping of the tie proceeds by rotating the chuck 5, and as the wraps progress outwardly from the chuck, the weight I acting on the strand 2 of the leader will cause the inner wire 9 to cut through the plastic coating I 0, until the wire 9 is engaging the core or wire ll of the main strand 3. Thus the wire 9 wraps around the wire I l as shown in Figure 3. With this arrangement I provide a wire on wire wrap which produces a permanent tie which will not unwrap and which is also compact and pleasing in appearance.

The plastic [0 which surrounds the core of the leader consists of a plastic, such as a synthetic polyamide (nylon), unplasticized vinyl resins (Vinyon), or cellulose acetate rayons, or the like. To further seal the tie I after it is completed and after the wire is cut off at the outer end, I then heat the plastic sheath Ill and then press or roll this sheath, preferably between the fingers and While the plastic is warm, thus fusing the plastic around the inner wrapped wires and producing a tightly sealed and compact tie. The fusing of the plastic coating around the tie area will also assist in holding the wrap and preventing the wires from unwrapping under strain.

In fusing the plastic material around the wire, and particularly in the area of the tie l, I find it advantageous to also apply the same heat to the plastic coating ll) in the loop 4 which causes this plastic coating to harden and as a result increases the wearing qualities of the plasticin the area of the loop.

Having described my invention, I claim:

1. The method of forming a tie in a leader formed of a plastic coated wire, consisting of wrapping one end of the leader around the main strand, then placing a weight onthe said one end of the leader while forming the wrapped tie to produce a tension thereon, said weight causing the wire to cut through the plastic coating to form a wire to wire contact in the area of the tie.

2. The method of forming a tie in a leader formed of a plastic coated wire, consisting of wrapping one end of the leader around the main strand, then placing a weight on the said one .end of the leader while forming the wrapped tie to produce a tension thereon, said weight causing the wire to put through the plastic coating to forma wire to wire contact Lin the area of the tie, then'hea'ting the wrapped tie and'then exerting pressure on the tie while heated, thereby fusing the plastic coating throughout the area of the tie.
